Really strange that a BIOS from a different company with a lower (430w) advertised power limit allowed your card to push past 400w. Have you ever tried the Evga Hybrid bios? I really hope that changing to a 16pin connector will alleviate these problems from future generations. Pretty ridiculous that you're having to jump through so many hoops. This is something that should have been handled a year+ ago.

IIRC I think I tried it when I first got the card, but I went to try it again there and I can't flash it now because of that dumb exe package EVGA use and "The display adapter firmware is up to date." error. I believe the BIOS this card shipped with was on an earlier version. EVGA really should put in a manual override feature for flashing.
 
Unfortunately, no one has dumped the Hybrid 450w LHR .rom file to techpowerup. Unless anyone knows if a ROM file can be extracted from these exe files? https://forums.evga.com/E...S-Thread-m3407542.aspx

I think going with 3rd party BIOS might disable your safeguards on the GPU, unless that's already happening with the EVGA versions.

Yup.. and stupid thing is on the Evga 3090 Ftw3 ultra using their xoc 500 watt bios, I cant hit more then 460watts.. And best part is it will hold power limit from 424watts and up and tank the clock.

Though.. if I use the kingpin 520watt bios I can run over 500 watts! Barely ever does it report power limit hit and stable clocks.

That's really odd.  Were others able to hit 500w+ with the same GPU you're using?

Yeah.. and I have the Ek front and back water blocks and crazy low temps of 32-35c under load and mem temps in the low 30s.. everything is cold so no idea what the prob is other then uneven power Linea. 150 for 1 and 2 and 3 usually 90-100 max. 50-60 watts on the pcie slot.

Hey what was your best score on the Metro Benchmark BTW? I have a 3080ti and I'm just curious to see how close the scores are. I ran it last night at 4k extreme and max power draw was 416.9w but I don't remember the actual framerates.

BMJet posted a utility a long time ago that could extract the bios file, but it didn't work on the latest exe files last time I tried.

Did you flash both bios switch positions with a non-evga bios? If not, you could flash to the one with the EVGA bios and then dump the bios file out so you'd have it. Then flash that position back to whatever is there now.

I'd be surprised if any of the flavors of EVGA bios would behave differently.

Yeah I noticed that utility doesn't work now with those exe's. I'm positive when I first got the card I tried that Hydro BIOS as I was doing everything to try and get up to 450w power draw.
 
Happy enough sticking with the MSI BIOS, I've made sure that while power report tracking is broken that my power supply draw and temps are basically the same between it on the same Afterburner curve as the "450w" EVGA BIOS that maxes out at 400w. It is. So, even although the MSI BIOS doesn't report power draw correctly the card seems to show the same behaviour between both BIOS when not power limited.
 
Where it exels is obviously under situations where the card is power limited the MSI BIOS appears to be drawing upwards of 500w. I believe what must be happening is the card essentially has no power limit now and is instead limited by hard BIOS limits of what I think is 175w per pin, and I assume general PCB design. I don't think any 3080 cards can really draw more than around 500w max. Likely just micro-spikes above that, not sustained.
 
Safe? Who knows, but at least I have very good cooling so I'm not mixing the unfavourable combination of high power draw, high voltage and high temps. If EVGA would actually communicate with anyone who has bought their top of the line 3080 cards then maybe it wouldn't have come down to flashing an MSI BIOS on an EVGA card. At the very least this experiment has shown the physical card CAN draw more power, suggesting something has been designed in the EVGA BIOS to inconsistently allow these cards to operate up to 450w.
 
I've seen or heard of a few of them doing it, but again, zero communication means no one knows why.

I must say, those are some impressive temps.

you all do know that power draw does not equate into more performance

Yes we understand that.. but at the same time. The low power limit drops the clock down pre maturely.

Memory starts crashing Time Spy at 1100, so 1000~1050 seems to be the best I can do.

Core clock starts crashing at +165, so I presume if I want to attempt to push more there I would need to play around with the voltage curve. I did that with my 2080Ti (used a curve at 2100 1.093v) but for now I think I'll just stick with +150/+1000~1050.

GPU score above improving likely needs core going higher, not memory.

I'm surprised at how well these 3080s watercool, but then again this EK Block also has a nice nickel backplate with thermal pads for some additional passive cooling. My 2080Ti Corsair waterblock just had a standard backplate with no cooling properties.

(I abbreviated your post)
 
Test with even lower Memory OC to see if performance increases   ... crashes are an outright failure of OC.  These new cards will use "error correction" .... so performance can suffer - before crashing occurs ..(edit) If you push the RAM too hard
 
NVIDIA Boost has the last word in your boards final numbers, been that way for several generations.
 
As long as your MHz meet the advertised minimum it is Fine; after that it is the luck of the silicon lottery
 
Getting Max performance before hitting the Watt limit is a Good thing in my book
 
EDIT:  added = (edit) If you push the RAM too hard - for clarity

Thanks, I will keep that in mind! It's definitely the core causing the crashing, I've even tried with the memory slider at 0 lol.
 
Speaking of the core, Port Royal will happily complete with an unstable core https://www.3dmark.com/3dm/73317219? That's +200 lol
 
Time Spy is pretty much locked at +150 for me https://www.3dmark.com/3dm/73317601? I got a better score than earlier now though, GPU was up to like 19762.
 
 Max power draw with Time Spy
 

 
400w

My Timespy Graphics score is similar to yours but your Port Royal score is a lot better than what I got.
 
I got curious about my 3080 FTW3 card and ran TS and PR to see if mine was going over 400W.  I think the most I got was like 407 for a split second but generally stayed at 400W.  This is a recent RMA KR that I got back last week.

If you flash the MSI 3080 BIOS I linked to it will pull upwards of 500w, and possibly even spikes exceeding that. It's difficult to measure when the software reporting is broken, but my crude measurements based on my power supply draw seem to indicate that. As well as watching what my water temp and card temp get to.
 
Worth it? Well, if you have the cooling capacity and aren't happy EVGA released a broken 450w BIOS, why not? However, instead of playing around with 2200mhz at 1.1v with my new power overhead, I've settled for locking in at 2100mhz 1.050v. That can be maintained in Metro Exodus EE even with RTing, so seems like the best balance for me between power, thermals and not hitting power limit constantly in one of the toughest gaming loads.
 
2200mhz at 1.1v for example is power limited in Metro, games without RTing or less intensive games can maintain it (even most of early Timespy can), but it's really entering "bragging rights" only territory versus a good balance for daily running.

Not sure how that would fly with the Hybrid I have

The hybrid can handle 450-500w with good fans on the rad. Won't be quiet if you want to keep temps relatively low though. Remember that the same hybrid kit is used on 3080ti and 3090 FTW3's.
